CRISPR-U™ technology (CRISPR based), developed by Ubigene, is more efficient than general
CRISPR/Cas9 technology in double-strand breaking and homologous recombination. With CRISPR-U™, Ubigene has
successfully edited over 3000 genes on more than 200 types of cell lines.
Objective
To create a Human HLA-B Knockout
model in cell line by CRISPR-U™-mediated genome engineering.

Summary
HLA-B belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane. Class I molecules play a central role in the immune system by presenting peptides derived from the endoplasmic reticulum lumen. They are expressed in nearly all cells. The heavy chain is approximately 45 kDa and its gene contains 8 exons. Exon 1 encodes the leader peptide, exon 2 and 3 encode the alpha1 and alpha2 domains, which both bind the peptide, exon 4 encodes the alpha3 domain, exon 5 encodes the transmembrane region and exons 6 and 7 encode the cytoplasmic tail. Polymorphisms within exon 2 and exon 3 are responsible for the peptide binding specificity of each class one molecule. Typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. Hundreds of HLA-B alleles have been described.
